Are you getting bypassed by your team?

Since it is a transitioning phase for the team, ask them to keep you in loop on all relevant emails. But nothing beats the morning/start of day connect (informal) to get you what's really happening on the floor.

That may happen. Defining the structure of reporting and information flow as well as working on the organizational culture can be a solution. However, the environment, situations, causes and other factors need to be considered.

Until the team starts understanding the role of a PM and starts working well with a PM, there could be a blanket agreement between the PM and the team to Cc PM in every project related e-mail communication. Initially there will be a lot of email noise but in time, this should settle.
Alternately , assign a collaboration tool like share-point and encourage everyone to contribute to any project related discussions there .
Start Daily stand-ups with your team so you know the progress of the project .
In the team meetings have a standing agenda for Risks and Issues and encourage the team to report risks and issues promptly.
Before a Project Board/Steering committee meeting , ask your team members through a Calendar meeting invite , to make sure they give you the project updates for the month in a format that you require for your reporting.
Reinforce in every daily standup that team should come back to you in the first instance for any project related issues

PM role needs to implemented in letter & spirit. Only then we can answer / comment on the issue.

I concur with my colleagues here.
Even though we need to set expectations with team members at the beginning of the project, in my experience the most difficult aspects is basically managing those expectations. But I guess having confidence in the team can go a long way when it comes to managing stakeholder expectations
